FIELD OF THE INVENTION

The present invention is related generally to system of modular wall orfloor-mounted computing apparatuses that among other functions replacesstandard desktop PCs and enables computer user to access and use localand remote applications. More specifically, this invention relates to athin-client type computing apparatus built inside or in conjunction witha LAN or mains jack and connected to the building LAN systeminfrastructure or the existing power lines network at one side and tothe user interaction and peripheral devices on the other side.

BACKGROUND OF THE INVENTION

Desktop personal computers (PC) are essential working tools for manyprofessionals today. Desktop PCs brought not only access to informationand increased productivity, but also many inherent problems. Theseproblems include: high costs, low-reliability issues, poor informationand physical security, high power consumption and production of heat,noise, electromagnetic radiation, wasted space and poor centralmanagement. For these reasons and others, many organizations are seekingeconomical alternatives for desktop PCs.

In recent years, thin-client computing devices became a popularalternative for desktop PCs.

As thin-clients are built around the concept of remote processing andremote management, very little local maintenance and interaction isneeded to operate such devices. Thin-clients to some extent are capableof running local applications just like PCs.

Typical existing thin-clients are built as a desktop appliance connectedto the wall infrastructure with a power cord and with a Local AreaNetwork (LAN) cable and connected to the various desktop peripheralssuch as display, keyboard and mouse by additional cabling. Thin-clientsare connected via LAN or through Wide Area Network (WAN) to remoteservers where applications are run and data is stored. This type ofthin-client appliance takes desktop space and depends on connection ofvarious cables. Installation of This type of thin-client appliance iscomplex, time consuming and cumbersome due to the necessity to connectall the cables. Often, the device also needs to be physically secured tothe desk with additional physical securing cable and lock to preventtempering and theft.

Today there are some simple functions that designed to fit inside a LANor mains jack such as network switches and wireless Access PointsAnother option known in the art is the integration of the thin-clientinside the display device. While this option saves the video cableconnection and also reduces desktop space, it suffers from the inherentmaintenance problems of coupling the two functions together. This typeof integration tends to complicate maintenance and to increase thesolution price. It may be advantageous to separate these two functionsfor operational flexibility, ease of maintenance and proper assetmanagement.

Yet another option known in the art is the integration of thethin-client function inside the keyboard enclosure. This setup saves onecable—the keyboard connection. This solution is undesirable sincekeyboards are susceptible to mechanical failures and fluid damages,therefore maintenance problems using this combination are unavoidable.

Still another option known in the art is the integration ofcomputer/thin-client inside a touch pad or a mouse. This method isundesirable due to technical and operational problems including heavyweigh and high temperature that interfere with the mouse function andthe need to connect many cables.

Thus, there exists a need for a computing device which overcomes theseproblems and provides organizations and installation sites with a simplethin-client computing device that has minimum connected wiring and takesminimum desktop space. A computing device that can be easily deployedover existing or new network infrastructure, a device that requiresminimal and simple installation.

Generally, computing devices are constructed as one “mother board” towhich essential or optional boards or components are plugged usingconnectors or cables.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENT

The following detailed description is of the best presently contemplatedmodes of carrying out the present invention. This description is not tobe taken in a limiting sense, but is made merely for the purpose ofillustrating the general principles in accordance with the presentinvention. The scope of the present invention is best defined by theappended claims.

Further reference will now be made to the drawings, wherein exemplaryembodiments of the present claimed invention are illustrated.

Reference is first made to FIG. 1 illustrates a cross sectional view ofthe typical embodiment of the present invention showing the wall orfloor mounted insert-housing 100 a having network interface based onEthernet LAN.

Wall or floor-mounted insert-housing 100 a fit in a standard LAN jackhole (cutout) in the wall or in a floor-mounted box. Insert housing 100a is typically made of thin sheet metal or perforated plastic frame tosecure the inset mechanically and to conduct heat efficiently.

Insert housing 100 a may be retrofitted into a cutout made for astandard LAN connection point. This housing comprises a box 3,preferably made of metal for efficient heat dissipation. Box 3 issecured to the wall 4 by mounting screws 5 or similar friction basedfasteners. Box 3 may be mounted to a wall or floor plane. Alternatively,box 3 may be mounted to or in furniture or in a decorative box mountedto any other flat object. At one side preferably at the top or bottom ofbox 3 is at least one housing connector block 2.

Optionally, box 3 provides an EMI shielding against FR radiation emittedfrom or entering into the said box. Optionally, block 2 comprises EMIshielding and RF filters against FR radiation emitted from or enteringinto the said box.

Ethernet cable 1 provides LAN connectivity to the device. In thisembodiment the power for the device may be extracted from the LANsignals using Power Over Ethernet Powered Device circuitry or can besupplied by external wall mounted DC power supply. The LAN cable usuallyconnected to a network switch or hub at the other (far) side as will beshown in FIG. 4. The said Ethernet cable 1 is typically crimped orsoldered to the connector block 2 as will be shown in details in FIG. 20

Housing Connector block 2 may optionally include a location memory chip2 c. Additionally, housing connector 2 may also contain means forprotecting equipment from high voltage transients such as lightning, andmay provide isolation, shielding and grounding. Housing Connector block2 further containing some form of mating surfaces or contacts 2 b toform a low resistance electrical conductance with the insert housingcontacts 7 a of Mating connector in modular insert 7. Said matingconnector 7 may come in several configurations to mate with severalconfigurations of housing connector block 2.

Optional location memory chip 2 c may be a programmable device such asElectrically Programmable Read Only memory (EPROM) device or a presetread only device. Alternatively, a set of jumpers or miniature switchesmay be used. Location memory chip 2 c may be used by the remoteapplication servers or remote management servers (shown in FIG. 4) tocreate a “Location map” and to associate each insertable device with theinsert-housing location it was inserted into. Additionally, the inserteddevice may access information in location memory chip 2 c in order toadopt its function to its current location. Such functionality may beuseful in a dynamic environment where users may change their locationfrequently; equipment attached may be changed and moved etc. In thiscase there may be a high value for associating the user with the deviceand the device with the actual (physical) location using the Locationmapping described above. This may enable:

-   -   a. Location of the actual device in case of a device or network        failure that may require physical or logical troubleshooting.    -   b. Help in initial installation of various devices in the said        jack.    -   c. Definition of connected network resources based on the device        location—this may be useful for printers, scanners and other        network peripherals. The exact position of the installed        computing device may automatically assign the closest or most        comfortable printer location or scanner.    -   d. Easier audition by easily locating the organization deployed        assets.    -   e. The capability to limit access to high security materials not        only to specific users but also to specific rooms/building        location.

Similar results can be achieved by properly dividing the organizationnetwork into sub-networks and manage ports in managed LAN switchesThough this type of management is less flexible and less reliablecompared to the method of using location map of the current inventionwhich may operate independently of any network configurations orresources.

Interchangeable modular insert 600 is configured to fit inside the box3. Optional decorative frame 602 may be installed if space permitting.Typically for smaller installation space the decorative frame 602 wouldnot be installed. Plurality of variations of modular insert 600 may fitinto the said box 3. Few variations will be shown in the followingfigures. For example, modular insert 600 may be a computing apparatussuch as thin-client type computing apparatus. Modular insert 600 shownin FIG. 1 comprises a mating connector 7 in its back that mates with thehousing connector 2 to exchange all necessary signals to and from themodular insert 600.

The installation and operation processes can be explained using therelevant drawings. In the preferred embodiment, a standard floor orwall-mounted LAN jack can be either converted to the preferredembodiment configuration or pre-built while the building is being builtto enable quick installation of a computing apparatus. The LAN cabling 1is typically Category 5 or higher twisted pairs shielded type. The hole(cutout) in the wall or floor surface 4 is typically drilled incompliance with NEMA-WD6 standard cutout or other relevant standard. TheLAN cable 1 is usually stripped crimped and pressed into a terminalblock that is part of the housing connector block 2. Another option toachieve electrical connection between the LAN cabling and the installedhousing connector, especially useful if the jack is already installed,is to connect a short jumper cable between the existing RJ-45 LAN jackand the connector block of housing connector block 2 thus avoiding theneed for manually stripping and crimping processes. This method may beparticularly useful in the case that an existing LAN system is beingretrofitted from conventional LAN jacks to the LAN jacks of the presentinvention.

The housing connector is then secured to the housing box 3 to enableelectrical connection with the inserted module 600 through its matingconnector 7 and its spring contacts 7. The assembled housing 100 a isthan inserted into the LAN jack cutout and secured to the wall or floorsurface 4 by screws 5 or any other type of friction fasteners.

Though this cupper LAN based installation method would be relevant tolarge majority of the organizations, still there may be a need toprovide similar solution in cases that the whole LAN or segments of itare based on optical fibers.

Therefore another similar embodiment of the present invention shown inFIG. 2 which shows a insert-housing 100 b specifically for opticalfibers 1 a instead of cupper wiring based LAN presented above.

FIG. 1 a. illustrates a cross sectional view of another embodiment ofthe present invention showing the wall or floor mounted insert-housinginstallation heat conducting decorative frame and tempering detectoroption.

In the exemplary embodiment, heat conducting decorative frame 602 a isoptionally comprises of heat conductive material such as metal ofsufficient thickness, preferably aluminum or copper. The decorativeframe is preferably in thermal contact with the housing, the insertabledevice or both and assist in dissipation of heat generated by computinginsert.

In the exemplary embodiment, decorative frame 602 a is optionallycomprises of key 2 g capable of interacting with housing 3 so as tosignal the proper installation or removal of said frame. For example,security detector 2 f may sense the insertion of key 2 g. For example,removal of key 2 g may cause electrical resistance to load the networkcable 1. The current in said cable may be sensed for example by powerover Ethernet power supply and set an alarm.

In some embodiment of the invention, decorative frame is locked byphysical locking device to the housing preventing removal of said framewithout special tool. Preferably, in this embodiment, said frame isconfigured to hold the insert in place and prevent its removal withoutremoving the frame first.

FIG. 2 illustrates a cross sectional view of an embodiment of thepresent invention showing wall or floor mounted insert-housinginstallation having network interface based on optical fibers. Thisfigure shows a wall or floor mounted installation of insert-housing 100b and modular insert apparatus 603 similar to the ones shown in FIG. 1but adopted to be connected to a fiber optic network.

Wall or floor-mounted insert-housing 100 b fits in a standard hole inthe wall or floor mounted box. Insert-housing 100 b comprises a box 3,which holds housing connector 2 b and enable insertion of modular insert603. Decorative frame 602 may be installed for esthetic reasons if spacepermits.

Fiber optic cable 1 a provides data connectivity to the device. Thefiber optic cable usually connected to a network switch or hub withoptical ports at the other (far) end. Optical fiber cable may compriseof a single fiber operating in duplex or two fibers, single or multimode type. Housing optical coupler 2 a at the back of box 3 contains oneor more optical couplers to enable good optical interface between theoptical transceiver 7 b on modular insert 603 and fiber optic cable 1 a.Housing optical coupler 2 a may also include location memory chip 2 c.Housing connector block 2 a typically also contains some electricalcontacts 2 b to mate with the insert housing contacts 7 a to supplyoptional power and location memory 2 c connectivity.

Mating fiber optic transceiver 7 b attached to the side of modularinsert 603 mates with the housing optical coupler 2 a to deliver allnecessary signals to and from the modular insert 603.

Preferably, a power cable 1 b supplies power to the insert-housing 100b. Preferably, a power cable 1 b is connected to housing connector 2 a.Alternatively, power to the modular insert 603 is provided externally,optionally via a connector on the modular insert.

Optionally housing optical coupler 2 a includes fiber optic transceiverfor optical to electrical conversion, thus enabling the use ofeclectically interfaced interchangeable modular insert 600 instead ofoptically interfaced interchangeable modular insert 603.

In this figure screws 5 which are used for anchoring box 3 to the wallare shown.

FIG. 3 illustrates another cross sectional view of an embodiment of thepresent invention showing wall or floor mounted insert-housinginstallation having network interface based on network over power lines.This figure shows a wall or floor mounted installation of main powerinsert-housing 100 c and main power modular insert apparatus 604 similarto the ones shown in FIGS. 1 and 2 but adopted to be connected to themains power outlet.

Wall or floor-mounted insert-housing 100 c fits in a standard hole inthe wall or floor mounted box. Insert-housing 100 c comprises a box 3,which holds housing connector 2 b and enables insertion of modularinsert 604. Decorative frame 602 may be installed for esthetic reasonsif space permits.

Mains electrical wires connected to the building electricalinfrastructure are crimped or otherwise connected to the main powerhousing connector 2 d which mates with main power mating connector 7 c.Electrical wires typically consist of: Live line 1 c, Neutral line 1 dand Ground line 1 e. Voltage at this area will reach 110 or 230 Voltsand is dangerous for the users. Therefore proper shielding, insulationand safety measures need to be taken in this area to protect the highvoltage AC lines.

FIG. 4 illustrates a high-level system diagram with one or more remoteservers, multiple network switches or hubs and multiple connected LANjack installed computer apparatuses.

System 300 comprises at least one server 8 which may be located on-siteover Local Area Network (LAN) or at a remote location over Wide AreaNetwork (WAN). In the case that the system implemented is usingthin-client inserts the server 8 may be an application server,presentation server, legacy host or a web server. If multiple servers 8are being used, a load balancing function may be added before theservers 8 to route new connections based on various real time and staticparameters such as current server load and capacity of each individualserver. Application server not only executes programs for the thinclients, but it also can provide the thin clients with access to all theresources available on the networks attached to the application server.The application server 8 delivers data to the thin clients including,but not limited to, graphics, encoded audio, and video which are decodedand displayed by the thin clients. The thin clients may deliver dataincluding, but not limited to, keyboard and control signals, pointer,and encoded audio and video data to the application server 8.

Network connection 9 connecting the said server 8 with at least onenetwork switch or hub 10. Network switch or hub 10 is connected tomultiple wall or floor mounted insert housings 100 a via Ethernet cable1. Network switch or hub may have an integrated power over Ethernetend-span circuitry or fitted with external Power Over Ethernet mid-spanpower injector device/s 11 attached to it downstream. Alternatively oradditionally, all or parts of the insert housings 100 a may be replaceswith optically interfaced insert housings 100 b connected to Networkswitch or hub 10 with optical fiber cables 1 a and optionally also topower cable 1 b connected to power supply 11 a or getting its power fromhub 10.

Typically, the LAN cables are routed through the floors, walls andceilings of the installation site to a centralized location where anetwork switches or hubs installed.

An insert 600 is inserted into at least in one of the housings 100 a(100 b). Inserts may be chosen from a list of available inserts such ascomputing devises 610, 650, etc. Preferably housing which are not in useare covered by blank cover 605.

It should be noted that plurality of standard LAN jacks may be connectedto the same network infrastructure without interfering with itsoperation. In a typical installation few or all of the installed orexisting LAN are replaced with insert housings 100 a or 100 b

FIG. 4 a illustrates another high-level system 310 diagram withbroadband router, one or more local or remote servers, and multipleconnected mains jack installed computer apparatuses.

System 310 comprises of a broadband modem/router/firewall/residentialgateway/set top box 205 that connects the system sites to the internet312, at least one remote server 8 or local server 8 a that may be astandard PC or a dedicated appliance. The server 8/8 a may be anapplication server, multimedia streaming server, presentation server,legacy host or a web server or any other type of server. Applicationserver not only executes programs for the thin clients, but it also canprovide the thin clients with access to all the resources available onthe networks attached to the application server.

The broadband modem/router/firewall/residential gateway/set top box 205connected to the site electrical system directly if equipped withnetwork over power lines interface or through an external network overpower lines interface box 208. This enables multiple of insert housings100 c typically replacing existing wall or floor mounted power jackswhile connected trough household main power line 1 c,d,e depicted hereas one line cable.

An insert 604 is inserted into at least in one of the housings 100 c.Inserts may be chosen from a list of available inserts such as computingdevises 720, etc. For safety, housing which are not in use are coveredby blank cover.

In addition the core layer typically contains an interconnect component141 to interface it with the next layer. Hot components 142 such as theprocessor, bridge and video controller chips may be located at the aftside of the PCB to assist in heat dissipation to the metallic case 138.Heat is better conducted to the cover through silicon greases layer orelastic heat-conducting pads 143. Metallic cover 138 serves both as anEMI shielding and as part of the mechanical structure of the apparatus.

The second layer is the Peripheral and Power layer 144 consisting ofAudio controller, I/O controller LAN transceiver, Power Over Ethernetcircuitry, various power supplies, USB hub, USB power switching andsupport circuits. This layer also contains the interconnect means to thecore layer 141 and additional interconnect means 145 to the next layer.Some signals are passing through this layer from the core layer to thenext layer.

This is an important feature to assure that the decorativeframe 602 will not be removed inadvertently or on purpose byunauthorized person.

The said three layers are typically connected mechanically by sets ofspacers not shown in this figure to form a rigid structure with inconjunction with the metallic cover 138.

FIG. 9 a illustrates a cross-sectional view of an additional embodimentof an insert 600 b according to an exemplary embodiment of the presentinvention. The implementation shown although is an example, represents areasonable arrangement to ensure small size, good electricalcharacteristics, lower costs and assembly flexibility.

Some or all inserts depicted as 600, 603, 604, 100 a, 100 b, 100 c, 610,630, 640, 641, 650 and 720 may share the same layered constructiondesign.

Core Printed Circuit Board 140 a preferably contains the Processor,Memory controller/bridge, Bus/Buses, Volatile memory, Non-volatilememory, Video controller, On-Board programming and testing port and LANcontroller. Other circuitry may be added to support the core functionsas needed.

The core layer 140 a connects to Front panel layer 146 through connector148 a. Hot components 142 such as the processor, bridge and videocontroller chips may be located at the outer side of the PCB to assistin heat dissipation to the metallic case 138. Heat is better conductedto the cover through silicon greases layer or elastic heat-conductingpads 143. Metallic cover 138 serves both as an EMI shielding and as partof the mechanical structure of the apparatus.

Optionally, metallic case 138 is a modular construction comprised ofsections. For example, core layer 140 a may be manufactured with asection of the case 138 a already mechanically and thermally attached.Inserting core layer 140 a into connector 148 a provided electricalconnection to front panel layer 146 as well as mechanical and thermalintegrity of the case. Power and LAN layer 144 a preferably consists ofinterface with house infrastructure. This layer preferably comprisesmating connector 7 a, LAN transceiver, Power Over Ethernet circuitry,various power supplies. This layer connects to Front panel layer 146through connector 148 b. Hot components 142 may be located at the outerside of the PCB to assist in heat dissipation to the metallic case 138b. Heat is better conducted to the cover through silicon greases layeror elastic heat-conducting pads 143. Metallic cover 138 b serves both asan EMI shielding and as part of the mechanical structure of theapparatus.

Optionally, metallic case 138 is a modular construction comprised ofsections. For example, layer 144 a may be manufactured with a section ofthe case 138 b already mechanically and thermally attached. Insertingcore layer 144 a into connector 148 b provided electrical connection tofront panel layer 146 as well as mechanical and thermal integrity of thecase.

Modular construction of allows replacement of only power and LAN layer144 a to change the configuration of the insert from one configured tofit into insert-housing installation with Ethernet LAN 100 a to aconfiguration that fits into Fiber based LAN housing 100 b or main powerinsert-housing 100 c.

Optionally, less power-consuming devices such as Audio controller, I/Ocontroller, etc, are located on central layer 149 which optionallyconnects to Connector Front panel layer 146 via optional connector 148c.

Decorative frame 602 may be assembled to enhance the installationesthetics if desired. As shown in FIG. 6 a the decorative frame 602 isbuilt around the front panel 41 in such way that it can only be removedbackwards when the insert is completely removed from the wall/floorhousing. This is an important feature to assure that the decorativeframe 602 will not be removed inadvertently or on purpose byunauthorized person.

The said three layers are typically connected mechanically by sets ofspacers not shown in this figure to form a rigid structure with inconjunction with the metallic cover 138.

It should be clear that modular construction of 600 a and 600 b allowsflexible reconfiguration of the inserts and using common modules indesign and construction of large number of inserts.

For example, replacing Connector Front panel layer 146 with “headless”front panel, with optionally removal of central layer 149, would terncomputing insert with power pass-through and LAN port to a headlesscomputing device 641.

Similarly, insert with larger or lesser computing power may be achievedby exchanging core layer 140 a

This exemplary embodiment of theinvention, is intended to be used as a standard LAN jack for VoIP phone,PC laptop etc. Power to the hub and to the downstream ports may beprovided by Power Over Ethernet method (such as IEEE 802.3af) from theconnected LAN infrastructure. It should be clear to a person skilled inthe art of electronics that the modular insert may be constructed withother number of LAN ports such as two, three or six, etc or with otherenhancements such as remote management and security functions.

FIG. 11 a illustrates a block diagram describing LAN Switch Function.

The network switch passes data frames received from a transmittingstation (either from the building infrastructure network or from theexternally connected clients) to a destination station based on theheader information and the received data frame.

The switch may comply with the IEEE 802.3, IEEE 802.3u, IEEE 802.3x,IEEE 802.3af industry standards or any other standard or functionaldesign. The switch may also comply with pre-standard High Power OverEthernet to provide power forwarding to the 4 ports. Switch may bemanaged on non-managed type as needed.

LAN Switch insert module 175 has a mating connector 7, 7 b or 7 cdepending on its interface type and is configured to fit in box 3 ofinsert-housing 100 a 100 b or 100 c such that its mating connector isengaged with corresponding housing connector 2 or 2 a respectively.Mating connector 7, 7 b or 7 c connected to Local Area Network 24transceiver (physical layer module) interface between the LAN controller(MAC) 22 and the LAN media connected to the apparatus through the matingconnector 7, 7 b or 7 c depending on its type. LAN Transceiver 24 may beconnected to the Local Area Network controller 24 by means of MediaIndependent Interface (MII) bus or by other interconnection buses. LocalArea Network 24 transceiver may support 100BASE-TX, 100BASE-FX, 10BASE-Tand Giga LAN or other LAN protocols.

Power over Ethernet Powered Device circuitry 25 extracts power from theLAN transceiver 24 to power all apparatus circuits. This circuitry maycomply with industry standards such as IEEE 802.3af or pre-standard HighPower Over Ethernet to operate in conjunction with standard powerswitches and hubs or midspan power injectors. This circuitry containsPowered Device (PD) modules such as input filters, rectifiers,detection, classification, isolation switch and isolated down-converterswitching power supply to reduce the LAN 48V power to low voltage stablesupply needed to power apparatus circuitry. This module may contain therequired logic and signaling required by the appropriate standards to beincorporated in such interface.

Optional Power Over Ethernet Power Sourcing Equipment (PSE) controller29 may be added to provide downstream ports with Power Over Ethernet.This may be useful to support connected IP Phones or other PoweredDevices. To enable full power downstream, the Power Over EthernetPowered Device module 25 need to be powerful enough. This can beimplemented with High Power Over Ethernet circuitry.

Local Area Network controller 24 connected to the main Internal Bus 18.This connection allows data received and transmitted through the LANswitch to be available on the internal bus 18 to communicate with thefixed infrastructure building LAN. Data is passed from the building LANinfrastructure 1 through the housing connector 2, Mating connector 7, 7b or 7 c, LAN Transceiver 24, LAN Controller (MAC) 22 to the InternalBus 18 and vice versa.

Typical network switch embodiment uses volatile memory as packet buffer193 to temporarily store the packets of data which it receives from theunits (end node or network switch) connected to it while the switchlogic determines how, when and through which port to retransmit thepackets. Each packet can be transmitted to only one destination address(a “Unicast” packet) or to more than one unit (a “multicast” or“broadcast” packet). For multicast and broadcast packets, the switchtypically stores the packet only once and transmits multiple copies ofthe packet to some (multicast) or all (broadcast) of its ports. Once thepacket has been transmitted to all of its destinations, it can beremoved from the packet buffer memory 193 or written over.

In the LAN switch insert embodiment shown here 4 ports are provided toconnect external clients to the LAN. To interface with these 4 ports, 4sets of LAN connectors are built in the front panel 177. Panel mayfurther include the LAN magnetics, EMI filtering and indicator LEDs.Each port is connected to its respected LAN transceiver (PHY) 24. EachPHY is connected- to its respective LAN Controller (MAC) 22 through anMII bus. All LAN controllers are then connected to the internal bus 18.

Packets received at each of the ports in the front panel 177 aretemporarily stored in receive packet buffers 193 by either the DMAcontroller 192 or directly from the internal bus 18. From the packetbuffer 193 received packets may be distributed to their destinationports by any convenient means through the switch fabric 191. The switchfabric 191 and the attached logic physically connect specific input portto specific output port for direct packet streaming.

Optional CPU 190 can be used as necessary to program and monitor theexact rules which are appropriate to control packet processing. However,typically once the switch logic registers are appropriately programmedor configured, the switch may operates, as much as possible, in a freerunning manner without communicating with CPU 190.

Optional Management Information Base (MIB) Registers 194, connected tobus are registers implemented in the switch system to enable remotemonitoring and configuration of that switch from remote sites usingstandard SNMP (Simple Network Management Protocol). In addition the MIBregisters enables collection and transmitting of ports statistics. MIBsare a collection of definitions, which define the properties of themanaged object within the device to be managed. Every managed devicekeeps a database of values for each of the definitions written in theMIB. It is not the actual database itself—it is implementationdependant. Definition of the MIB conforms to the SMI given in RFC 1155.Latest Internet MIB is given in RFC 1213 sometimes called the MIB-II.

FIG. 12 illustrates a computing apparatus insert module with anadditional LAN port 640 according to the preferred embodiment of thepresent invention. This insert module with pass-through LAN port 640 issimilar to computing apparatus insert module 610 as depicted in FIG. 6.

Computing apparatus insert module 640 has a mating connector 7, 7 b or 7c depending on its interface type and is configured to fit in box 3 ofinsert-housing 100 a, 100 b or 100 c such that its mating connector isengaged with corresponding housing connector 2 or 2 a respectively. Anoptional decorative frame 602 may be fitted if installation spacepermitting. Connector 2 (2 a, 2 d) provides power for operation of thevarious electronic circuitry inside the computing module 640 as well asdata link to the remote server 8. Computing apparatus insert module 640comprises a front panel 41 a with optional holes 43 for special removaltool. Insert module 640 is built so it could be easily inserted into box3 and locked. In the exemplary embodiment depicted in FIG. 12, insertmodule 640 is a thin-client apparatus connected to a server through itsmating connector and comprises at least few interface connections on itsfront panel 41 a.

A LAN port 45 is provided on front panel 41 a. This LAN port may be usedfor connection network enabled external devices such as Laptop computer,Voice Over IP phone or other LAN based device. Optional power forwardingoption may be installed to enable downstream powering of the connecteddevice. In that case the LAN jack 45 may be fitted with power indicatorto indicate that the connected powered device is receiving power.

This optionally RJ-45 LAN port may be used as a “Pass-through” or it maybe controlled by the processor within insert module 640. For example,insert module 640 may be used to provide Virtual Privet Network (VPN)over existing LAN, increasing data security for example by encryption ofthe data exchanged between the end user and host 8. Additionally oralternatively, insert module 640 may be used as “firewall” protectingthe LAN against intentional or unintentional attempts to performunauthorized communication. For example, inserted module 640 may beconfigured to assess the identity of any device or user connecting toLAN port 45, blocking any unauthorized use of the said port.

Optionally inserted module 640 is equipped with an auxiliary power inputjack 47 for connection of external DC power-supply.

Optional Link/Activity indicator 52 may be fitted on the front panel 41to provide a visible indication of the connected infrastructure(upstream) LAN status.

It should be noted that the exemplary configuration of FIG. 12 describesa typical embodiment of a thin-client computing apparatus insert modulewith an additional LAN port. For example, number of USB ports may varyor omitted. Alternatively or additionally, keyboard and mouse connectorsmay be used instead of USB connector. For example; IrDA Transceiver maybe omitted, Audio In or Audio Out or both audio connectors or resetswitch may be omitted and other connectors may be added. Monitorconnection may be replaced with other standard visual signal connectionssuch as RGB, video connection, S-video connection etc.

In some embodiments of inserted module 640 some of the elements: 602,42, 44, 47, 48, 49, 50, 5, 152 and 53 may be omitted.

Specifically, in an embodiment of the invention, inserted module 640 isused as firewall or to provide Virtual Privet Network (VPN). In thisembodiment, some or all the elements: 42, 44, 47, 48, 49, 50, 51 and 52may be omitted.

An optional use of LAN port 45 is to enable standard or proprietary dataencryption between the connected device and remote network resources.

Such implementation may be useful to high-security applications wheretunneling or additional encryption required for externally connecteddevices.

FIG. 12 a illustrates the use of computing apparatus with pass-throughLAN port for secured data system 340 according to an embodiment of thepresent invention.

In this embodiment, secured data system 340 is built similarly to system300 of FIG. 4. Preferably, computing apparatus insert modules withpass-through LAN port 640 are inserted in plurality of boxes 3. Modules640 are programmed to provide one or more preprogrammed securityfunctions such as encryption-decryption, Virtual Private Network,Firewall etc. Therefore external computing device 944 can operatesecurely connecting to server 8 or 8 a on different (lower or higher)security network 1, network switch, hub or router 10 and Backbonenetwork 9.

Preferably, external devices 944 are located in a user secured area 946,accessible only to trusted personnel. Data exchanged between module 640and external device 944 is in unsecured form.

External computing devices 944 may be desktop PC, Laptop PC,thin-client, Terminal, network printer, scanner or any other computingdevice having a network port. Cable 942 is optionally connected betweenthe external computing devices 944 LAN port and the LAN ports 45 onmodules 640. Downstream Power option enables the computing apparatus 640to power the connected external device 944.

Further enhancement of the embodiment described in FIG. 12 b. Thisembodiment 341 include a network switching function 655 a and 655 b(physical or logical—through software) that under certain conditions maybridge between the LAN cable 942 a and 942 b connected to the externalcomputing device 944 a and 944 b and LAN 1x and 1 y on the other side.

In FIG. 12 b the two different options are shown through two externalcomputing devices 944 a and 944 b. External computing device 944 aconnected to the secured computing insert 640 a by LAN cable 942 a.Secured computing device 944 a is shown configured in such way that itsLAN switch function 655 a connected the external computing device 944 adirectly to the LAN 1 a.

The other external computing device shown 944 b is accessing higherclassification data and therefore it is connected through LAN cable 942b to the second secured computing device 640 b. This device internal LANswitch function 655 b was configured locally or remotely by a managementfunction to connect the external computing device 944 b securely througha VPN tunneling 945, to a local or remote server 8. In this state thedata passed between secured computing device 640 b and the securedserver 8 is encrypted and isolated from the standard network connectedto other clients such as 944 a.

This implementation enables the secured computing insert 640 a and 640 bto serve as a secured switching device according to remote or localmanagement and security commands. The system may sense the type ofexternal computing device 944 a or 944 b and it user using them and thendecide locally or remotely if that user will be able to access thenetwork 1 directly or open a VPN and access special server/s 8.

This system implementation is specifically useful to enable anend-to-end high security data exchange inside a lower security networkwith much lower risk of data leakage between the two networks. With bothnetwork co-exist on the same infrastructure, a single network may beused instead of two physically isolated networks.

A reverse implementation of the above system enables the device 944 toconnect to low security server 8 (such as a web server on the internet)without any risks to a higher security network 1 (intranet), networkswitch, hub or router 10 and backbone network 9.

Preferably, computing device used for secured data application is“heedless” type. FIG. 12 c shows the front panel of headless computingdevice 641 having only few of the features and connections of computingdevice inserts 610 or 640. In this example only LAN connector 45 andreset button 49 are present on front panel 184. Internal block diagramof the headless computing device is optionally missing the block ofunused option. Optionally, the front panel of headless computing device641 is similar to or indistinguishable from Pass through LAN jackmodular insert 620 seen in FIG. 7.

Having no keyboard or video connections reduces the cost of headlesscomputing device 641 and increases data security by making it difficultto access or reprogram the device externally, thus providing addedsecurity and immunity against unauthorized intrusion. Optionallyheadless computing device 641 comprises of specific hardware forencryption/decryption of information and may be specifically designedfor that purpose.

FIG. 12 d illustrates a block diagram of a computing apparatus withpass-through LAN option 130 according to a preferred embodiment of thecurrent invention.

This may be useful to supportconnected IP Phones or other Powered Devices. To enable full powerdownstream, the Power Over Ethernet Powered Device module 25 need to bepowerful enough. This can be implemented with High Power Over Ethernetcircuitry.

This type of implementation is specifically useful in case that theparticular installation infrastructure provides only a single LAN portper user. The internal hub allows both the computing apparatus 135 ofthe present invention and IP telephone to share the same port andoptionally share the same remote power source.

Insert 670 comprises a front pane 60, optionally equipped withquick-release buttons 61 (instead of access holes 43 for special removaltool) to release the mechanical lock function after testing andprogramming completed. Preferably, the two buttons 61 are pushed inorder to release the tester insert from box 3.

Optionally front panel 60 equipped with few indicators. For example:

-   -   A LAN cable indicator 62 may be in a form of color-coded light,        for example a green/red LED configured to illuminate when LAN        cable tested to function correctly (no open and no shorts). In        the preferred embodiment, red light will be illuminated in case        of LAN wiring fault exists. In this case the fault details will        appear on the device's display 70.    -   A Power over Ethernet indicator 63 may be in a form of a        green/red LED configured to illuminate green when Power over        Ethernet signals available and functioning correctly for the        tested port. Optionally several properties of the Power over        Ethernet are tested such as voltage, current capacity and noise        level and detailed results will appear at the device's display        70.    -   Communication speed indicator 64 may be in a form of multicolor        LED configured to illuminate in amber color when 10 Mbps link is        available; in green when 100 Mbps link is available; in blue        when 1 Gbps link is available and not illuminated when non of        the above is available.    -   Location indication LED 65, illuminating wham activated remotely        by the management system. This function may be useful to confirm        from remote help-desk or maintenance console that the tester        programmer device connected to the proper port.        Additionally, front pane 60, optionally equipped with an RF        wiring trace push button 73. Upon pushing this push-button, the        device generates strong RF signal on the LAN port. This enables        technicians to trace connected LAN wiring using special RF        detector. Signal strength provides guidance to the LAN wiring

Tester modular insert 670 may be configured to perform some testingfunctions and report the results using its indicators independently oftester controller 700. Tester also can report test and programmingresults to the management server if LAN port is functioning properly.Tester can also PING to remote servers as additional testing for thatport.

More testing and programming function are available when testercontroller 700 is connected using flexible cord 67 to the controllercable connector 66 on front panel 60.

Alternatively, tester modular 670 may have to be connected to testercontroller 700 in order to perform any of the tests.

Tester controller 700 comprises a keypad 69 with alphanumeric andfunction keys, a display 70 such as Alphanumeric LCD display andoptionally indicators such as:

-   -   Battery Low indicator 71 which may be in the form of a red color        LED, Illuminating when internal (optionally rechargeable)        batteries have reached a critical condition.    -   Power On indicator 72 which may be in the form of a green LED,        Illuminating when the tester controller is turned on.

Alternatively, all indicators may be located on tester controller 700.

To test a housing 100 a (100 b or 100 c), tester insert module 60 isinserted into the installed box 3. When fully inserted the tester insertmodule locks mechanically into position and make electrical (andoptical) connection to housing connector 2 (2 a).

Upon turning the tester controller on, several illuminated LEDsindicates the status of the installed jack under test and its cabling.

If jack's location memory chip 2 c is already programmed, the locationstring can be read on the controller display 70.

The user can program a desired location string by entering the stringthrough the keypad 69 and press a specific function key to reprogram thejack location memory chip.

User may program unique location parameters into the location memorychip to enable automatic location detection and mapping. Data inlocation memory chip 2 c may be used to enable or disable specificfunctionality of the housing or the inserted module which is inserted tothe housing. For example; in order or prevent unauthorized access to theLAN, a housing may be disabled unless a valid data is entered intolocation memory chip 2 c, additionally or alternatively, the types ofinserted module which may be functioning within a specific housing maybe limited by data is entered into location memory chip.

Location mapping allows the server to continuously monitor the statusand existence of inserted module in each housing and to issue an alarmnotice if any of the modules is tempered with or removed. Alarm noticemay include information on the physical location of the module inquestion.

Alternatively, data in location memory chip may be factory set, andtester and programmer system may be used to read said information inorder to create the location mapping.

Another function of the tester and programmer system is to enable TCP/IPping to a remote host for testing.

Yet another option is to enable blinking of location indication LED 65by remote management system to verify that the tester/programmer isactually connected to the right jack.

After the jack was tested and its location memory chip programmedsuccessfully it is ready for installation of any modular insert from theplurality of matching options.

Yet in another embodiment is to enable the jack by programming thememory chip with a valid ID number. Without such number any computingdevice inserted to the housing would not work properly.

Yet in another embodiment the programming the memory chip is done with avalid ID number specific to the insert to be inserted into the jack. Anyother combination of computing and housing would not work properly.

In some embodiment the testing and programming device comprises ofspecific hardware necessary for programming the location memory chip,thus preventing unauthorized reprogramming of said memory chip.

In some embodiments location memory chip define the class of thehousing. For example, a class may restrict access to some data orfunction. For example, a housing may be define to belong to a classrestricted to have “read only” operation without authorization to writeor delete data on the server, restricted to exchange only VoIP data,etc. In this embodiment, some location within the organization may havedifferent restrictions or authorization. For example, classifiedinformation may be accessed only by users reside in specified locationsregardless of the computing devices used.

It is clear to a person skilled in the art that testing and programmingfunctions may be achieved using other tools and system implementations.For example, functionality of the housing may be tested by inserting acomputing apparatus insert module 610, 640 or 650.

is clear to a person skilled in the art that security measures disclosedin the current invention are preferably augment security measures knownin the art such as the use of a password or a hardware key.

Future active inserts, designed to fit into wall housing 3 may use thesame or similar method of extracting power. Mating connector 7 or 7 bconnects to housing connector 2 or 2 a respectively.

Mating connector 7 or 7 b couples the insert circuitry to the LANinfrastructure and to various other external functions. With IEEE 802.11af attached network DC voltage between 36 and 57V will be presentbetween the TX (pins 3-6) and the RX (pins 1-2) sides or between sparecable pairs pins 4-5 and pins 7-8. The TX and the RX signal pairs areconnected to LAN transformer 211. This transformer provides voltageisolation and impedance matching with the connected LAN transceiver(PHY) 22. The LAN transceiver 22 sends and receives packets through theTX and the RX pairs respectively. With little effect on the LANfunctioning, Diode full rectifiers 212 takes the input DC voltage andrectify it to ensure proper polarity. The resulted DC voltage—nominally48V is then passed through an EMI filter 213 to reduce the incoming andoutgoing electromagnetic interference level. From there it is passedthrough a detection circuitry 214 that intended to signal the connectedswitch or power injector Power Sourcing Equipment circuitry that thisparticular device matches the Power Over Ethernet standard. Propersignature typically achieved using a 25 K Ohm resistor. From thedetection circuitry DC voltage typically connected to the classificationcircuitry 215.

From the isolation circuitry 216the DC power typically connected to an isolated DC to DC converter 217.The isolation required by certain standards to avoid certain safetyhazards. Typically 1500 VAC isolation required between the media side(wall LAN infrastructure) and the device circuitry. This isolationbarrier is shown in the figure as dashed line 220. Isolation on the dataside achieved using LAN transformer 211 while in the DC to DC it istypically achieved by a fly-back transformer 218 and an opto-couplerfeedback device 219. Negative DC output of the isolated DC to DCconverter 217 is connected to the main device ground while positive side(typically 5V or 3.3V) 221 connected to the various internal powersupplies and to the various electronics circuitry. An array of DC to DCand or linear power supplies is used to further generate additional lowvoltages needed for the device operation. In this embodiment DC to DCpower supply A 222 generates voltage A through its output 223. DC to DCpower supply B 224 generates a different voltage B through its output225. Linear power supply C 226 generates yet a different voltage Cthrough its output 227.

It should be noted that the choice of the number and types of powersupplies s (Linear vs. DC to DC power supply) is made according to thecircuit requirement. For example, if the required output is close to theinput voltage then it is better to implement a linear power supplyinstead of DC to DC converter.

As an alternative, 5V DC power may be connected to the 5V power plane221 with certain logic from a panel mounted DC jack. This enables properdevice operation in cases that Power Over Ethernet infrastructure is notavailable.

FIG. 17 presents a more detailed possible implementation of the networkover power lines input blocks according to the current invention.

Network over power lines implementation block diagram 178 gives moredetails as to the inner construction of blocks 26, 33 and 34 seen inFIG. 8 a.

7 c is the mating connector adapted to withstand the high voltage (110to 230 VAC) connected to the housing connector. Pin 1 of the connectoris the phase, pin 2 is the ground and pin 3 is the Neutral. When theinsert is installed in the housing box power from the building mainslines connected to these 3 pins. Input power connected to the couplingtransformer 230 and to the AC to DC power supply 235 that powers theapparatus. The AC to DC power supply circuitry reduced the input voltageto 5V DC 221 to power the internal DC to DC down converters 222, 224 and226. These DC to DC power supplies generates the internal DC voltages223, 225 and 227 needed to power the apparatus internal circuitry.Coupling transformer 230 and internal transformer inside the AC to DCpower supply 235 isolate the rest of the apparatus from the highvoltages available in the power lines. Isolation barrier 220 serves as asafety measure with isolation of at least 1500 V between the two sides.Anything other than useful network data carried over the power lines isfiltered by the High Pass Filter 231 that connected to the couplingtransformer 230. The filtered signal is then connected to the AnalogFront End (AFE) 232. The AFE contains additional adaptive filtering,multiplexer, receiver, driver, analog to digital, digital to analog andAGC circuitry to interface between the digital side of the basebandmodule 233 and the analog signals of the coupling transformer 230.Baseband module 233 contains the processor, MAC, PHY, DSP and additionalcircuitry to handle all networking layers and activities. It is thenconnected to the other insert circuitry using direct bus interface, USB,MII or any other common interface.

FIG. 20 illustrate in further details the cross sectional view of thehousing connector block 2 presented in FIG. 1. The primary function ofthe housing connector is to electrically interface between the buildingLAN cable 1 and the removable insert housing contacts 7 (not shown herefor clarity—showed at FIG. 1).

LAN Cable 1 is fixed mechanically to the connector module by block 400preferably made of metal that serves both as a friction pad to securethe cable 1 to the module 2 and also as a shielding component to connectthe cable shield to the housing shield 3 properly. The said block 400may conduct high currents in case of lightning strike and therefore itmay be built of solid metal. The top cover 425 secured the cable to theblock 400 by providing positive down-word pressure on the cable.

Metal blades 410 are fitted to enable cable crimping to each of theeight conductors 401 contained in the shielded LAN cable 1. A specialhand tool may be used to push each conductor to its metal blade 410 toprovide good electrical contact through the conductor isolation layer.Each of the eight blades is color marked 402 to show the properconductor that should be connected to that blade. Various otherelectromechanical methods may be used to secure and connect the LANcable 1 conductors 401 to the housing connector 2.

The eight blades 410 are soldered into the small contacts PCB 412. Thistwo-sided PCB serves as a component carrier and conductor for thehousing connector 2. On the top side the eight blades connected and onthe bottom sides there are eight to twelve gold plated connector strips404 positioned in such way to be in full contact with the insert matingcontacts 7 (not shown here for clarity). Also on the bottom side of thisPCB 412 there are optional lighting spark gaps 415 to protect the insertcircuitry from high voltage spikes induced by lighting strikes. Lightingspark gaps 415 may be implemented simple printed patterns on the PCB orby attached Through Hole or SMT components. Electrical signalsconnection from the PCB 412 top side to the bottom side is achieved bymeans of via holes such as 418.

Optional location memory chip 2 c may be fitted inside the connectorblock to further improve the housing functionality. To reduce cost thesaid chip 2 c may be assembled directly on the top side of the PCB 412using Chip On Board technology. The chip 2 c may be covered by anencapsulation layer to protect it from mechanical and humidity damages.

Cover 425 provides mechanical protection for the assembly and furthersecure each of the eight crimped conductors 401 to the appropriate blade410. The cover may also serve as a shield and to secure the LAN cable 1to the metal block 400.

To facilitate for easy installation and support, the connector block 2is secured to the housing part 3 by a removable means.

It should be clear to a man skilled in the art that similar constructioncan be made for other types of LAN or power standards. For example,number of conductors may vary without departing from the generalconfiguration according to the current invention.

Specifically, main household lines 1 c, 1 d and 1 e may take the placeof the eight Ethernet lines of 1. In this case, proper high voltageinsulation and higher current-carrying capacity connectors should beused.
